產(chǎn)品特性：
All electrical parameters are regarded as standards of the loop output signal, high precision standards and standard source integration design, covering all the functions of the standard source and can output high precision pure sine wave voltage, current, phase, frequency, power, power factor, etc. of electrical parameters signal, built-in high precision standard electric energy meter;
Can be used to test a variety of single (three) phase electronic, mechanical energy meter, multi-function electric energy meter, multi rate watt hour meter, all kinds of electric energy acquisition module, the use of electric collection terminal and other measurement terminal products.
Electric energy cumulative, go test, black label, starting and creeping test range of standard features, can be used to verify the absence of pulse output electric energy meter or meter.
Can arbitrarily set or set required voltage, current, frequency, phase and amplitude value and the flexibility to choose the parameter test and arbitrary regulation set by the magnitude of the, and 2-51 high precision harmonic output, convenient for harmonic test.
The instrument has the function of limiting current protection, power amplifier protection, voltage short circuit protection, current circuit protection, power amplifier thermal protection, etc., can prevent the instrument from all kinds of operation or abnormal situation caused by fault.
The instrument can store 200 sets of electrical energy meter test data, through the RS232 interface and the computer management software can be easily connected with the computer to achieve intelligent operation.
